Hey there! Does it help to try changing the language? Settings > General > Language & Region > iDevice Language. Try setting it to English if its set to a different language to test.
If this helps, please let us know, so that we can get this on our team’s radar again. Here’s the older thread about the issue.
I’ll close the other one down so we can get updated tracking for after the 16.4 patch 
Thanks for the report!
